Parade's End9pm, BBC2

It's a case of drama played as farce tonight: drama because Sylvia insists on visiting France to see Christopher; farce because this is the first world war, and working behind the lines preparing soldiers for battle involves an exhausted Christopher in the labyrinthine idiocy of the military. The situation is compounded by Sylvia's mischief-making and Christopher's unerring ability to court dishonour through being honourable. Fabulous television, thanks largely to Tom Stoppard's pitch-perfect script and beautifully judged performances, most notably Roger Allam's exasperated General Campion. Jonathan Wright

Fairport Convention: Who Knows Where The Time Goes?9pm, BBC4

It scarcely seems credible that, when founding member Simon Nicol took the stage at Islington's Union Chapel last March, it was for Fairport Convention's 45th anniversary concert; in one form or another, the Fairport franchise really has been around that long. A recording of the greatest hits gig follows this profile of the band that launched the careers of legends Richard Thompson and Sandy Denny, and whose 1969 album, Liege & Lief, remains a thing of spellbinding wonder.

Moone Boy9.30pm, Sky1

Another full-series offshoot for one of Sky's Little Crackers, Moone Boy riffs on the childhood of IT-Crowd and Bridesmaids star Chris O'Dowd. Newcomer David Rawle stars as the adorably hapless Martin Moone who, when not trying to give mouth-to-mouth to dead chaffinches, is trying to protect himself from the school bullies by setting his sister up with a bullier of bullies, with shambling assistance from O'Dowd's imaginary manchild friend. A touch too twee for its own good, it's destined to be pigeonholed as the latest of Sky's ever-rolling conveyor-belt of gentle comedies, though in fairness the writing feels far sharper than yer Mount Pleasants.

QI 10pm, BBC2

A fresh selection of alliterative posers from quintessential inquisitor Stephen Fry. This opening episode of series J sees newcomer Victoria Coren join regulars Bill Bailey, Jimmy Carr and Alan Davies to take on the world of jargon. While QI feels less of a rare treat now there's the option of watching old episodes 10 times a day on Dave, new episodes are still a welcome sight, if only to keep up to date on delicious trivial titbits such as the surprising etymology for several well-known txt-speak terms.

Alan Carr: Chatty Man10pm, Channel 4

The anti-Piers Morgan returns with a new series of giggle and chat. What's that? You prefer the real Piers? Oh, OK, watch him "interrogate" Roger Moore in the new series of Life Stories over on ITV1 at 9pm. Carr's effort is likely to be a more frothy and glamorous affair, as the inescapable Gok Wan joins him for a gossip about his new dating show, while Pink performs her new single. Camp laughs guaranteed, or your money back. Hannah Verdier

Dawson Bros Funtime10pm, BBC3

Web comedy quite literally means web comedy for Dawson Bros. Funtime, a sketch show almost entirely indebted to matters online. So Facebook, Twitter and YouTube all figure in various vignettes. Even MegaUpload gets a mention. Despite this it largely skirts the right side of funny. Produced by some of the team behind Charlie Brooker's Wipe series, and featuring Peter Seranfinowicz as narrator, Dawson Bros Funtime might need to get out more, but it's still worth 27 minutes of your time.
